The Truck Covers USA American Roll Cover is awesome!! I looked at the pros and cons of many different retractable covers before making my purchase. The American Roll cover is one of the most expensive, but worth it in my book. Everything is about as "heavy duty" as you can get on a retractable bed cover. Installation took me a couple hours as I had a little trouble getting my rails level. The rest of the installation was relatively easy.
2011 F150 6.5 bed
No issues with installation as others had. only needed help to set unit, (so not to scratch anything) Fit is great with provided shims. I did not want to drill holes in the metal so I used all the supplied tubing to route front drains out plastic inserts in front of bed, a trip to the hardware got fttgs and tube to route back drains into front tubing. Cover is leaking somewhere, noticed water dripping from sides after rain but haven't checked into that yet. Cargo is very secure! Wish the cover came with the inside release, instead of having to unlock tonneau using key even with tailgate down. Special order, I'm told. Kinda bogus considering cost.
